Trax recently made a comeback with their single, Let You Go and if you are a frequent viewer of music shows in recent weeks, you will have noticed SNSD's Seohyun playing the piano for them during their performances. SM Entertainment has just uploaded a UCC video on their official Youtube channel of Trax's Jungmo doing a cover of SNSD's recent hit single, Oh! with his electric guitar, to return the favour for helping them and it sounds really slick. Who's for Trax and SNSD having a collaboration sometime in the near future? http://www.youtube.com/watch?v=rsO0eS1Us14 Many thanks to ellondra for the tip.
